Silicon Motion Technology has begun sampling its single-channel, ultra high performance controller solution for USB 3.0 flash drives, the SM3267, which promises to deliver a data transfer rate of up to 160 MB/s read, a 30% to 50% improvement from most single-channel USB 3.0 flash drive controllers in the market today. Silicon Motion's SM3267 provides high-speed data transfer rates of up to 160 MB/s read and 60 MB/s write. Integrated crystal and power ICs, including a 5V to 3.3V LDO and a 5V to 1.2V DC-DC, allows for 25-30% lower USB flash drive device temperature compared with other USB 3.0 flash controller products in the market. In addition, by eliminating the crystal oscillator and power ICs, the total BOM cocts of USB 3.0 devices are lower by up to 15 to 20%.

The controller supports the vast majority of NAND flash, including 2y/1x/1y nm TLC, MLC, high speed Toggle, and ONFI DDR NAND manufactured by Samsung, Toshiba, SanDisk, SK Hynix, Micron and Intel. It has also passed both USB-IF compliance testing and WHCK (Windows Hardware Certification Kit) tests for Windows 7 and Windows 8.

The SM3267 is available in Chip-on-Board (COB) and in a 48-pin QFN green package with manufacturing-ready turnkey solutions designed to fit mainstream USB 2.0 flash drive modules.
